(20014)internal Error: Proxy: Error Reading Status Line From Remote Server
weird. One of my clients has been consistently getting 502 Bad Gateway errors (without fail and in every browser), but only on one particular page of my Rails site, she can access the rest of the pages normally. Also, everybody else (including people on the same company network) can access the same page fine. Also, the production.log does not contain any trace of an error, it says the page was rendered 200 proxy-initial-not-pooled OK. What could possibly be causing this??? EDIT: I have double-checked that other Rails errors, such as trying to call up the details of a product id that doesn't exist, result in a 404 error instead. ruby-on-rails share|improve this question asked Jun 15 '12 at 15:45 Sprachprofi 769420 A 502 may have nothing to do with your app internally, as it indicates an invalid response was received from another server while trying to process the client's request. –cdesrosiers Jun 15 '12 at 15:54 Do you have a reverse proxy (like nginx) in front of the Rails server? If so, check those logs. –Abe Voelker Jun 15 '12 at 15:54 Have you visited the client and watched the error happen in situ? –edralph Jun 18 '12 at 12:51 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote accepted I found it. This was an error with page headers (session object -> cookie) getting too large. I'm using Facebook authentication and was storing the Facebook user session in the session object. For this one person, her personal information on Facebook was too long, so that she was getting this error while everybody else was fine. I fixed the error by only storing the Facebook ID i

I'm able to resolve the problem by deleting the PID files, restarting mongrel, the proxy server received an invalid response from an upstream server. apache reverse proxy and/or redeploying. But this time, I'm not able to resolve the situation. I'm able to pull up pages on the the proxy server received an invalid response from an upstream server tomcat site on one request, but then the next will produce the 502 Proxy Error, so it seems as though one of my clusters is "stuck" someone.

Reason: Error reading from remote server Apache/2.2.3 (Red Hat) Server at 67.192.59.219 Port 80 I've tried killing the processing and restarting mongrel, but I'm still having the same problem. Can someone help by pointing me in the right direction of what to https://www.ruby-forum.com/topic/160743 look for in log files, or how to solve this issue? I'm using the basic recipe laid out in the Pragmatic Programmers Guide and on all my Rails projects, I run into a problem of one or more of the clusters not restarting because a PID file already exists...is this a known bug in the version of Capistrano I'm using?

It is running on Nginx, installed with Passenger, and is hosted on a error reading status server running Ubuntu 10.04. It seems that the errors are becoming more and more sparse, but they're still causing a problem. I am guessing that it has something to do with buffer size, but am not sure. I know there are a few other questions on here from people with the same problem, but it seems to be very peculiar. Thanks in advance for any help or suggestions.
